Overview Many partners – American Embassy, US Military, Nuclear Regulatory Commission KEY: Partnership with US Military for AMS – Government of Japan: multiple ministries KEY: Collaboration with MEXT for AMS DOE Role – Monitor environment AMS Ground Field expedient early warning system to be used while reactors were considered unstable – Assess – Advise Radiological consequence management advice for US ambassador and US Military Division of labor among DOE teams – Field team: small, interdisciplinary, experienced, adaptable – Home team: multi-lab – Headquarters: handle political pressures

Aerial Monitoring What was done Fixed wing and helicopter Up to 3 aircraft per day DOE & GOJ joint survey Why it was done Map ground deposition out to 80 km from FDNPP Support evacuation, relocation, agricultural decisions

9
End State US Military and Government of Japan to continue monitoring activities as needed – Japanese trained & equipped to fly DOE AMS – Japanese equipped with an enhanced laboratory analysis capability – DOE continues to support Japanese and US Military from Home Team

Field Team Activity Successes DOE deployed with little notice, no advance preparation, and began operations immediately DOE was able to perform on-the-fly analysis to deal with multiple ongoing releases, unknown source terms, challenging terrain as well as non-technical pressures. DOE Scientists developed customized products for US Military (data products, InField Monitoring System). DOE scientists embedded with Japanese scientists to create joint data products. Augmentation of CM teams
